Reports indicate that the joint geometry and loading configuration aff
ect the crack growth behaviour of specimens. In an attempt to study th
e above effect, three specimen geometries are selected; cruciform join
t under tension (CJT), side end notch under tension (SENT) and under t
hree-point bending (SENB3) load. Results show that all three geometrie
s have different fatigue strength and fracture mechanics parameters, a
lthough their weld-metal chemistry and mechanical properties are the s
ame. Further tests are needed to establish this relationship quantitat
ively.
